Roses are among the most beloved and iconic flowering plants in the world, celebrated for their captivating beauty, vibrant colours, and rich cultural symbolism. Belonging to the genus Rosa in the Rose family (Rosaceae), there are over 300 wild species and thousands of cultivated varieties, ranging from compact miniature roses to towering climbing specimens.

Roses are recognised by their layered, often velvety petals and enchanting fragrance, which can range from sweet and delicate to rich and heady. They come in virtually every colour, each traditionally carrying symbolic meaning — red for love and passion, white for purity, yellow for friendship, pink for admiration, and orange for enthusiasm.

Beyond their ornamental value, roses have a long history of practical use. Rose hips — the fruit of the rose — are rich in vitamin C and are used to make teas, syrups, jams, and preserves. Rose petals are edible and commonly used as garnishes, in salads, and to flavour confectionery. Rose oil, distilled from petals, is one of the most prized ingredients in the perfume and skincare industries.

Roses are perennial plants that, with proper care, will reward gardeners year after year with spectacular blooms. They are vigorous growers that benefit from regular pruning, feeding, and pest management to maintain their health and flower production.

How To Grow

Growing Roses

Roses are rewarding plants that repay careful establishment and consistent care with seasons of spectacular bloom.

Choosing a Variety

Select a variety suited to your available space and purpose. Hybrid teas produce large, classic single blooms; floribundas bear clusters of flowers; shrub roses are robust and low-maintenance; climbing roses are ideal for walls, arches, and fences.

Planting

Roses are most commonly planted as bare-root stock during dormancy (late autumn to early spring) or as container-grown plants at any time during the growing season. Choose a site with at least six hours of direct sunlight per day. Roses prefer well-drained, fertile soil enriched with well-rotted compost or manure.

Dig a planting hole wide enough to accommodate the roots without bending, and deep enough so the bud union (the swollen point where stems meet rootstock) sits just at or slightly below soil level. Backfill with improved soil, firm gently, and water thoroughly.

Watering

Water deeply and consistently, particularly during dry periods. Water at the base of the plant rather than overhead to keep foliage dry and reduce the risk of fungal disease. Apply a 5–7 cm layer of organic mulch around the base to retain moisture, suppress weeds, and regulate soil temperature.

Feeding

Roses are heavy feeders. Apply a balanced or rose-specific fertiliser in spring as growth begins, and again after the first flush of flowers. Reduce feeding in late summer to allow the plant to harden off before winter.

Pruning

Prune established roses in late winter or early spring just as buds begin to swell. Remove dead, damaged, or crossing canes, cut out weak growth, and open up the centre of the plant for good air movement. Make cuts at a 45-degree angle just above an outward-facing bud. Deadhead spent blooms throughout the season to encourage continuous flowering.

Winter Care

In colder periods, mound mulch or compost around the base of the plant to protect the roots and bud union from hard frost. Climbing roses can have their canes loosely tied and wrapped with horticultural fleece if particularly cold conditions are expected.

Harvesting

Harvesting Roses

Roses offer two distinct harvests: cut blooms for display or use, and rose hips for culinary and medicinal purposes.

Harvesting Cut Flowers

Timing: Harvest blooms in the early morning when stems are fully hydrated and temperatures are cool. Cut when buds are just beginning to open rather than fully open — this maximises vase life.

Technique: Use clean, sharp secateurs or scissors. Make a diagonal cut just above an outward-facing leaf node, leaving at least two sets of leaves on the remaining stem to support continued growth and photosynthesis. Place cut stems immediately into a bucket of clean, lukewarm water.

Conditioning: Before arranging, re-cut the stems underwater at a diagonal angle to maximise water uptake. Remove any foliage that would sit below the waterline in the vase to prevent bacterial build-up. Use a floral preservative in the vase water to extend longevity.

Aftercare: Change vase water every two to three days and re-trim stems to keep them taking up water. Keep arrangements away from direct heat, strong sunlight, and ripening fruit, which emit ethylene gas that shortens flower life.

Harvesting Rose Hips

Rose hips — the fleshy fruit that forms after flowers are pollinated — are ready to harvest in autumn once they have turned a deep red or orange colour and feel firm but slightly soft. Use scissors or secateurs to snip hips from the plant. They can be used fresh or dried for teas, syrups, jams, jellies, and preserves. Note that the seeds inside hips are covered in fine hairs that can cause irritation — always strain infusions and processed hip products thoroughly.

Harvesting Rose Petals

Petals for culinary use should be gathered when the flower is newly opened and at its most fragrant. Choose petals from plants that have not been treated with pesticides. The white base of each petal can be slightly bitter and is often trimmed away before use.

Common Problems

Common Rose Problems

Pests

Aphids: Soft-bodied insects that cluster on new growth, buds, and the undersides of leaves, sucking sap and causing distorted growth. Blast off small infestations with a jet of water, or treat with insecticidal soap or neem oil.

Thrips: Tiny insects that damage petals, causing streaking and browning, particularly on light-coloured varieties. Good garden hygiene and removing affected blooms helps control them.

Scale insects and spider mites: Can infest stems and foliage, particularly in dry conditions. Spider mites cause fine webbing and bronzed, stippled leaves. Maintain humidity around plants and use appropriate horticultural treatments if severe.

Sawfly larvae (leaf-rolling and slug sawflies): Caterpillar-like larvae that skeletonise or roll leaves. Remove by hand or treat with a suitable insecticide if numbers are high.

Diseases

Black spot (Diplocarpon rosae): A very common fungal disease producing dark spots on leaves, which then yellow and drop. Improve air circulation, avoid overhead watering, collect and dispose of fallen leaves, and apply a suitable fungicide if necessary.

Powdery mildew: A white, powdery fungal coating that appears on young shoots, leaves, and buds, particularly during warm days and cool nights. Improve airflow, avoid water stress, and treat with a fungicide if needed.

Rose rust: Orange or rusty pustules on the undersides of leaves, with yellowing on the upper surface. Remove affected material and treat with a copper-based fungicide.

Rose dieback: Caused by fungal pathogens entering through pruning cuts or damaged stems. Always use clean, sharp tools and cut back to healthy wood to manage dieback.

Other Issues

Poor flowering: Often caused by insufficient sunlight, over-feeding with nitrogen (which promotes foliage at the expense of blooms), or failure to deadhead spent flowers.

Nutrient deficiencies: Yellowing leaves may indicate iron or magnesium deficiency, particularly in alkaline soils. Use a chelated rose feed or foliar spray to correct.
